commit0736299d09upstream. Register read of TCPC_RX_BYTE_CNT returns the total size consisting of: PD message (pending read) size + 1 Byte for Frame Type (SOP*) This is validated against the max PD message (`struct pd_message`) size without accounting for the extra byte for the frame type. Note that the struct pd_message does not contain a field for the frame_type. This results in false negatives when the "PD message (pending read)" is equal to the max PD message size.
